It's interesting to hear the different takes you get from coaches vs what you get from media. Johnson has been a decent, not great, blocker before and he still is now. If he does make the team it will be because of that and his experience in pass routes too. I've just heard a lot of good things about Will Johnson, he's a sleeper but if the Steelers really want to shake things up then maybe WJ gets the nod over DJ.
Watching DJ last year try and block as a FB just never really gave me that much confidence; perhaps part of is was Arians though but still.
